To all wiz-0m it may concern:

Be it known that I, Dononr. L. KITTRELL, a citizen of the United States,residing at Nashville. in the county-of -Davidson and State ofTennessee, have 'invented new and useful Improvements inCheck-Controlled Apparatus, of which the following is a specification.

This invention relates to improvements in check controlled apparatus andhas particular application to apparatus for controlling `the operationof pumps for vending gasolene, although I wish it'to be understood thatmy invention, in its useful application, may be used in connection withapparatus other than pumps.

In carrying out the present invention, it is my purpose to provide checkcontrolled apparatus which will be found especially useful incontrolling pumps for dispensing gasolene and whereby the pump may beoperated to deliver the gasoleneonly after a coin of the properdenomination has been -inserted in the apparatus and whereby apredetermined quantity only of the gaso-A lene will be delivered tothepurchaser.

It is also my purpose to provide apparatus of the class described whichwill operate eciently and effectively under all conditions to controlthe operation of the pump or other apparatus, which will be capable of avariety of uses and wherein the component parts will be so arranged andcorrelated as to reduce the possibility of derangement to a minimum.

With the above and other objects in view, the invention consists in theconstruction,

combination and arrangement of parts here-- inafter set forth in andfalling within the scope of the claims.

In thel accompanying drawings; Figure 1 Vis a view in side elevation ofcheck controlled apparatus constructed in accordance with the presentinvention, the same beingt the parts in the positions they occupy when acoin is inserted in the casing. Fig. 4 is a cross sectional view on theline 4 4 of Fig. 2. Fig. 5 is a similar view on the line 5 5 of Fig. 2.Fig. 6 is an enlarged fragmentary vertical sectional view through theapparatus.

Referring now to the drawings indetail, 1 designates a base constructedof any suitable material, while 2 indicates a supporting frame arrangedat one end of the base 1 and upstanding therefrom and in the form ofaninverted U. Arranged across the face of the inverted U-shaped frameand suitably fastened tothe legs thereof adjacent to the upper end ofthe frame is a cross bar 3. Slidably mounted within vertically aliningbearings carriedby the upper end of the frame 2 and the cross bar 3respectively is a vertical rod 4 capable of vertical sliding movementand having the lowerend thereof connected with the upper extremity ofthe piston rod 5 of the pump 6, the piston rod working within an openingformed in the base 1. -Formed on one edge of the rod 4 are teeth 7,While ivoted upon the cross bar 3 is a lever 8 having the lower endformed with'a dog 9 and thev upper end weighted as at 10 and acting tohold thedog end of the lever normally in engagement with the teeth 7.Formed upon the opposite edge of the bar 4 are teeth 11 and pivoted uponthe cross bar 3 adjacent to the teeth 1l isadog 12 normally held out ofengagement with l the adjacent ratchet .teeth 11. 'Ihe teeth. 11 arearranged reversely to the teeth 7. Also formed on one edge of the rod 4is a series of gear teeth 13 and meshing with the teeth 13 is a pinion14 mounted upon a shaft j ournaled in the upper end of the frame 2 andconnected to one end of this shaft is a crank handle 15 whereby thepinion may be rotated to slide the rod. Secured to the base 1 andprojecting upwardly therefrom is a vertical standard disposed adjacentto one edge of the frame 2 and pivoted upon the upper end of thestandard 1G is a horizontal beam 17. Secured to one end of the beam 17is a yoke 18 and pivoted between the limbs of the yoke 18 is a coinreceptacle 19 provided with a downwardly projecting curved wing 20.rll`he opposite end of the beam 17 is offset downwardly as at 21 andslidably mounted upon the offset portion of the beam is a weight 22 andbalancing the coin receptacle 19.

23 designates a vertical` rod having the lower end thereof slidablymounted within an opening in the base and the upper end slidably mountedin an opening in the upper extremity of the frame 2. djustably mountedupon the rod 23 is a pin 24 disposed adjacent to the end of the odsetportion 21 of the beam 19 and normally holding such end of the beamagainst downward movement underthe action of the counterweight 22. Alsoupsta'nding from the base 1 adjacent to the A-yoke end of the beam andbelow such end is a short standard 25 and pivoted upon the upper end ofthe'standard 25 is a trip 26 connected by means of a wire 27 with oneleg of a bell crank lever 28 pivoted upon the leg of the frame 2adjacent to the opposite end portion of the beam. Pivoted'to theremaining leg' of the bell crank lever and projecting upwardly therefromis alink 29 having the upper end thereof connected with ana-rm' 29secured to the rod 23. 4Secured to the lower end of the rod 4 andprojecting outwardly therefrom and loosely surrounding the rod 23 is alug 32. 36-d`esignates an arm secured to the beam 17 at the fulcrumpoint of suchbeam and projecting upwardly therefrom, while 37 indicatesa wire-connecting the upper end of the arm 36 with one endof a link 37.The other end ofthe link 37, is connected through a -pin and slotconnection '30 with the-dog end of the lever 8, and by a wire 31 withthe dog 12.

33' designates a casing inclosing the mechanism just described andformed' with a coin slot 34 yfrom which extends a coin chute 35 leadingto the receptacle 19.

ln practice, the receptacle 19 is' normally disposed contiguous to thelower end of the chute 35, while the dog end of the lever 8 holds therod 4 normally at its limit of downward movement and prevents movementofthe rod under lthe action ofthe handle. W'hen it is desired to actuatethe rod 4 a coin of the proper denomination is deposited in the slot 34'and falls down the chute 35 into the rceptacle 19 and when the coinenters the receptacle the counterweight 22 is overbalanced and the beam17 swung about its pivotal Vconnection with the standard 16 and in thismovement ofthe beam 17 the arm 36 pulls upon the wire 37 and so actuatesthe link 37 with the e'ect to move the dog end of the lever 8 out ofengagement with the teeth? and the pawl 12 into engagement with 4theteeth 11. The crank handle 15 may now be rotated and in the rotation ofthev crank handle the rod 4 will be moved in one direction to move thepump piston from one end of the cylinder to the other. As the rod 4moves upwardly the lug 32 slides upwardly along the rod 23 and engagesthe pin 24 with the effect to elevate such rod 23 and in the continuedupward movement of the rod, the pin 24 is carried into engagement withthe adjacent end of the beam 17 and swings the yoke end of the beamdownwardly. Simultaneously with vthe downward movement of the yoke endof the beam 17, the trip 26 is swung upwardly through the medium of thearm 29', link 29, bell crank lever 28, and the wire 27, incident to theupward movement of the rod 23 to which the arm 29 is connected, and inthe downward movement of the yoke end of the beam 17, and the upwardmovement of the trip26, the wing 20 is struck-by the trip vwith theeffect to tilt the coin receptacle to discharge the" coin therefrom.

Upon the discharge of the coin from the receptacle 19 thecounterweight22 swings the beam 17 in the reverse direction and the arm36 and wire 37 restore the dogs to normal positions, thereby permittingthe rod l to be moved in the opposite direction under the action of thecrank handle to move the piston toward the opposite end of the cylinder.Upon the movement of the pawls to normal positions the bell crank leverand trip 26 are likewise restored to their original positions so thatthe above cycle of operations may be repeated when another coin isdeposited in the slot.

lVhile I have herein shown and described one preferred form of myinvention by way.

of illustration, l wish it to be understood that I do not limit orconfine myself to the precise details of construction herein describedand delineated, as modification and variation may be made within thescope of the claims and without departing from the spirit of theinvention.
